Why is concentrated sulfuric acid used instead of concentrated nitric acid?

Hi. The sulphuric acid is used in the preparation of hydrogen chloride {HCl} and nitric acid {HNO3} because it is a non-volatile{ it has a high boiling point} and HCl and HNO3 are volatile acids.

Why is sulphuric acid used in the preparation of hydrochloric acid and nitric acid?

Concentrated sulphuric acid has a high boiling point (356°C). So, it is considered to be non-volatile. Hence, it is used for preparing volatile acids like Hydrochloric acid and Nitric acids from their salts by double decomposition.

Why is concentrated sulphuric acid preferred to acids?

Answer:Sulphuric acid is used. This acid is preferred to other acids because of its dehydrating properties.

What is the purpose of using concentrated sulphuric acid when preparing chlorine?

Answer : Concentrated sulphuric acid is a very effective drying agent. The chlorine obtained as the product from the above reaction contains traces of water vapour, and hydrogen chloride (HCl) vapours.

Why concentrated sulphuric acid is not used in preparation of hydrogen?

Conc. sulphuric acid is not used in the preparation of hydrogen as it will produce sulphur dioxide.

Why is concentrated sulphuric acid used in the preparation of hydrogen chloride?

Dilute sulphuric acid will react to produce hydrogen gas. Increasing the concentration will increase the rate of reaction. Since the product is in another phase (hydrogen is a gas) too rapid a reaction brings a risk of overpressurization and explosion. (This was once an issue with car batteries).

Why is sulphuric acid used as dehydrating agent?

Concentrated sulphuric acid is used as a drying and dehydrating agent because it has a strong affinity for water and thus it absorbs water quickly. It being a hygroscopic substance absorb water from other substances without dissolving in it, so it is considered as a good dessicating or drying agent.

What process is used to prepare chlorine?

Chlorine can be manufactured by the electrolysis of a sodium chloride solution (brine), which is known as the Chloralkali process. The production of chlorine results in the co-products caustic soda (sodium hydroxide, NaOH) and hydrogen gas (H2). These two products, as well as chlorine itself, are highly reactive.

Why is water used in the preparation of chlorine?

Chlorine gas is passed through water to remove any gaseous HCl that may be present after it is synthesized.

Why don’t we use concentrated sulphuric acid in the laboratory preparation of hydrogen using zinc granules?

sulphuric acid is not used because zinc reacts with concentrated acid to form sulphur dioxide gas instead of dihydrogen.

Why is hot concentrated sulfuric acid not used in the preparation of hydrogen?

Dilute sulphuric acid will react to produce hydrogen gas. Increasing the concentration will increase the rate of reaction. Since the product is in another phase (hydrogen is a gas) too rapid a reaction brings a risk of overpressurization and explosion.

What happens when sulfuric acid is added to nitric acid?

In preparations that call for concentrated sulfuric acid, it usually has the role of trapping moisture. If dilute sulfuric acid is used, then nitric or hydrochloric acid may still be produced (since they boil more readily than the sulfuric acid), but they will contain water.

Why is concentrated sulfuric acid used as a strong oxidizer?

Best answer is concentrated sulfuric acid is a strong oxidizer. Also produces much sulfur dioxide as well. It has to be in a water solution to best react with metals to produce hydrogen. Somewhat diluted sulfuric is usually used.

Is it better to dilute or concentrated sulfuric acid?

Thus, dilute sulfuric acid would be sufficient. In fact, it would be better since it ionises to give an even more acidic solution. However, chemists choose to use the concentrated one instead, suggesting that the role of sulfuric acid is more of a reducing agent.

Is sulphuric acid a reducing agent or reducing agent?

Thus, dilute sulfuric acid would be sufficient. In fact, it would be better since it ionises to give an even more acidic solution. However, chemists choose to use the concentrated one instead, suggesting that the role of sulfuric acid is more of a reducing agent. Is there a reason for this? In fact, sulfuric acid is not a must.
